Debate over non-cashflow related accounting issues + timing of income deferring profits to 2nd half = SP has plummeted despite good track record and outlook. It seems the former issue has eroded trust in management, including their assurances that they're on track with full year profits.
To me, cashflow, long-term profits and management of the company are far more important than short-term accounting treatments and management of investor PR. All worst case scenarios priced in and a lot of upside potential for patient investors here imho.
